Role of Part 4985111 Flexible Hose in Engine Systems

The 4985111 Flexible Hose is an essential component in various engine systems, facilitating the efficient transfer of fluids and gases while accommodating the dynamic movements and vibrations inherent in engine operation.

In the context of the breather system, the flexible hose connects the breather to other components, allowing for the release of pressure and the evacuation of contaminants from the crankcase. This connection ensures that the breather can effectively manage the airflow, preventing the buildup of pressure that could lead to oil leaks or engine damage.

Within the crankcase system, the hose plays a significant role by providing a flexible link between the crankcase and other parts of the engine. This flexibility is vital for maintaining a sealed system, which is necessary for the proper functioning of the crankcase ventilation system. It helps in directing crankcase gases to the intake manifold or another designated area for safe disposal, thereby reducing emissions and improving engine efficiency.

In plumbing applications, the 4985111 Flexible Hose is used to connect various fluid lines, such as oil, coolant, or fuel lines. Its flexibility allows it to navigate around obstacles and absorb vibrations, which protects the integrity of the plumbing system and prevents leaks.

For the crankcase breather system, the hose ensures a secure and flexible connection between the breather and the intake tract or another suitable outlet. This setup allows for the efficient removal of blow-by gases from the crankcase, which helps maintain clean oil and reduces the risk of contamination.

Overall, the 4985111 Flexible Hose enhances the reliability and performance of engine systems by providing durable, flexible connections that can withstand the rigors of engine operation.

Conclusion

The 4985111 Flexible Hose by Cummins is a critical component in the fluid transfer systems of commercial trucks, particularly in engines like the ISM CM876.
